Making a tall artboard (with a shorter Viewport Height) will let you scroll up and down, but it can't snap to specific vertical places. Drag interactions are currently left/right, not up and down, so you can't drag up/down to go between artboards.
Do a search on https://adobexd.uservoice.com to see if there's already a feature request for this. If so, you can upvote it. If not, you can create a new one.
